After a dozen people were arrested at one club, police are now using some new technology to help identify the drug.

Molly is a dangerous drug similar to ecstasy, which can come in several forms including powder, crystal and pills. The user can feel euphoric, but can also die due to increased blood pressure and heart rate.

“It seems like it’s that club drug; the reemergence of the 1990s rave scene again,” said Det. Brian Coen, Quincy Police Dept.

Detectives focused on one marina bay nightclub last month that plays techno music and kids jam the dance floor.

“We did a lot of undercover surveillance work because we were seeing overdoses of Molly,” said Chief Paul Keenan, Quincy Police Dept.

Police caught 12 people, some charged as dealers. William Naumenko is doing 60 days behind bars on a probation violation after being arrested a second time.

Using a cutting edge laser drug detection device called TruNarc, an undercover detective in Quincy is able to test drug samples on the spot.

“When we hit the scan button the laser will strike that sample in question,” one detective said.

“They’re running, what, six months behind right? The instant knowledge allows us to know exactly what we have on the street,” another detective said.
